/* CodeLine FAQ Accordion — frontend styles. Scoped under .cfa-accordion.
 *
 * Panels animate with a CSS grid-rows collapse (0fr -> 1fr) instead of
 * JS-measured pixel heights. This means the open/closed visual state is
 * driven entirely by the `data-open` attribute + CSS, so it can never
 * drift out of sync with aria-expanded, get stuck at a stale pixel
 * height, or require a transitionend callback to finish.
